Impact of the Antenna on the Sub-Terahertz Indoor Channel Characteristics: An Experimental Approach

no code implementations7 Mar 2024 Priyangshu Sen, Sherif Badran, Vitaly Petrov, Arjun Singh, Josep M. Jornet

The results highlight the multi-faceted impact of the antenna gain on the channel and, by extension, the wireless system and, thus, show that an antenna-agnostic channel model cannot capture the propagation characteristics of the THz channel.

Design and Validation of a Metallic Reflectarray for Communications at True Terahertz Frequencies

no code implementations11 Sep 2023 Sherif Badran, Arjun Singh, Arpit Jaiswal, Erik Einarsson, Josep M. Jornet

Wireless communications in the terahertz band (0. 1-10 THz) is a promising and key wireless technology enabling ultra-high data rate communication over multi-gigahertz-wide bandwidths, thus fulfilling the demand for denser networks.

Modeling Interference for the Coexistence of 6G Networks and Passive Sensing Systems

no code implementations27 Jul 2023 Paolo Testolina, Michele Polese, Josep M. Jornet, Tommaso Melodia, Michele Zorzi

In this paper, we provide the first, fundamental analysis of Radio Frequency Interference (RFI) that large-scale terrestrial deployments introduce in different satellite sensing systems now orbiting the Earth.


Terahertz Communications Can Work in Rain and Snow: Impact of Adverse Weather Conditions on Channels at 140 GHz

no code implementations29 Aug 2022 Priyangshu Sen, Jacob Hall, Michele Polese, Vitaly Petrov, Duschia Bodet, Francesco Restuccia, Tommaso Melodia, Josep M. Jornet

Next-generation wireless networks will leverage the spectrum above 100 GHz to enable ultra-high data rate communications over multi-GHz-wide bandwidths.

Novel Spectrum Allocation Among Multiple Transmission Windows for Terahertz Communication Systems

no code implementations6 Jul 2022 Akram Shafie, Nan Yang, Chong Han, Josep M. Jornet

We also show that a further data rate gain can be obtained by optimally determining the unused spectra at the edges of TWs, as compared to avoiding using pre-defined spectra at the edges of TWs.

TeraHertz Band Communication: An Old Problem Revisited and Research Directions for the Next Decade

no code implementations25 Dec 2021 Ian F. Akyildiz, Chong Han, Zhifeng Hu, Shuai Nie, Josep M. Jornet

The key aspects presented in this paper will enable THz communications as a pillar of 6G and Beyond wireless systems in the next decade.

Spectrum Allocation with Adaptive Sub-band Bandwidth for Terahertz Communication Systems

no code implementations10 Nov 2021 Akram Shafie, Nan Yang, Sheeraz Alvi, Chong Han, Salman Durrani, Josep M. Jornet

Aided by numerical results, we show that by enabling and optimizing ASB, significantly higher throughput can be achieved as compared to adopting equal sub-band bandwidth, and this throughput gain is most profound when the power budget constraint is more stringent.

Climate Change Sensing through Terahertz Communications: A Disruptive Application of 6G Networks

no code implementations6 Oct 2021 Lasantha Thakshila Wedage, Bernard Butler, Sasitharan Balasubramaniam, Yevgeni Koucheryavy, Josep M. Jornet

Climate change resulting from the misuse and over-exploitation of natural resources has affected and continues to impact the planet's ecosystem.

Xilinx RF-SoC-based Digital Multi-Beam Array Processors for 28/60~GHz Wireless Testbeds

no code implementations3 Aug 2020 Sravan Pulipati, Viduneth Ariyarathna, Aditya Dhananjay, Mohammed E. Eltayeb, Marco Mezzavilla, Josep M. Jornet, Soumyajit Mandal, Shubhendu Bhardwaj, Arjuna Madanayake

Emerging wireless applications such as 5G cellular, large intelligent surfaces (LIS), and holographic massive MIMO require antenna array processing at mm-wave frequencies with large numbers of independent digital transceivers.
